string command

Hi,

I'm writing a code that wil receive and send a string through serial port (UART). The setup of the ARM is good. Now, I would like to know if is there a command, function, code, and so one that I can write the message as the way we speak and the program converts it to decimal ASCII and the opposite too.

example:

send 'ARM microprocessor'

I was told that Keil have a key for this but I didn't find it.

I'm using MCB2300 with LPC2368.

Thanks a lot.
